People believe that there should be some kind of relationship between God and man.
1.) One level is that God is the Creator and humanity is the creation. And that is certainly true.
2.) Some go a little further to believe that God is Lord and His people are His servants. And that too has true ground.
3.) Some understand another truth - that God is King and His people would be subjects or citizens of God's kingdom.
These relationships are all biblical. And perhaps they bring man and God closer and closer together. But the ultimate relationship that God's salvation brings many people do not see.
That is that God and man are
mingled so that man lives God and God lives in man.
it is the revelation of the mingling of God and man that the religious mind often cannot and will not accept.
We even might say that the purpose of religion is to keep God and human beings separated. This is the mission of the Jehovah's Witnesses. They want to make sure that there is no union in life between God and man. But this is because they do not see how full, how extensive, how effective and how total is the redemption of Christ.
They don't see God as coming as God and man mingled. And they do not see God's eternal purpose to go being mere Creator / creature or King / subject or Master / servants to
Bridegroom and Bride.
The kingdom is the
"eternal kingdom of our Lord and Savior Jesus Christ" (2 Peter 1:11). And this Godman reigns not temporarily but
"forever and ever"
"The kingdom of the world has become the kingdom of our Lord and of His Christ, and He will reign forever and ever." (Rev. 11:15)
Forever God will never put off from Him the humanity with which He clothed Himself in incarnation. He will eternally be not only the only begotten Son but the Firstborn among many brothers. His salvation has brought God and man so close as to defy the natural religious mind.
